    Slide 213: Berry aneurysm
     
    It’s called a berry aneurysm because it looks like a little berry. It’s not named for Thadeus J. Berry. Very thin walled, you can imagine what will happen when this thing ruptures.

    See this slide with the virtual microscope.

    It’s easy to see the aneurysm expanding off the edge of this elastic artery. Where in the vascular system do you anticipate seeing such a aneurysm? What would be the outcome of a ruptured berry aneurysm?

    The insert image shows changes of atherosclerosis. Note the cholesterol slits in the fragmented plaque.
